Windows ping syntax

 

Parameters

-f switch sets the Do Not Fragment bit on the ping packet. By default, the ping packet allows fragmentation.

In the ping command, the –l option means to send the buffer size in bytes. It is followed by the number of bytes for buffer size.

You can combine  -f and -l to guess the maximum frame size by trial and error.

 

Possible replies

“Packet needs to be fragmented but DF set”

The frame is too large to be on the network and needs to be fragmented.

 

Examples

ping www.moviescope.com –f –l 1500

About pmgallardo

I studied Computer Science at University of Salamanca. Since then, I have been working first as developer and then as SAP consutant. This blog is about problems I dealt when using computers, and more important, the solutions I found. Whenever I am on an issue and suddenlly I have a flash that leads me to a solution, I document my discoveries in a post.
